Two soldiers come to the commander of the unit with some kind of bottle. He looked and asked:
"And what is this?"
"Well, the vodka is kind of strange, Comrade commander."
He opened the bottle, sniffed, poured it into a glass, took a sip. He tasted it, finished his glass and said:
"It's just vodka, I can't see anything wrong with it."
"Comrade ensign also can't see anything after it."
